Experimental result analysis on Stanton number, friction factor and thermal performance of three sides inclined roughened with those of smooth and three sides glass covered solar air heaters have been represented. Results show that the values of Stanton number are more in three side’s inclined roughened one, leading to an increase of 69% to 57% in thermal performance as compared to three side’s glass covered smooth one. Friction factor increases by 29% to 41%. The effect of roughness and flow parameters (p/e, e/D, Re, α) on heat transfer, friction factor and thermal performance has been shown and discussed. The uncertainties in the values of Stanton number and friction factor yield the uncertainty of +1.29% to +6.06% in the values of thermo hydraulic performance.
